A Complete Guide to Oracle Apex: Building Low-code Enterprise Applications

If your enterprise runs on Oracle Database, you already have access to one of the most powerful low-code platforms on the market to deliver enterprise-grade applications: Oracle APEX. Yet despite its great capabilities to enhance business processes, many enterprises are still unaware it exists.

This guide shows directors, IT, leaders, and technical teams exactly what Oracle APEX is, where it fits in the Oracle stack, and how to use it to build secure, scalable applications fast. You’ll get a clear view of core capabilities, features, integration patterns, and pragmatic next steps—so you know how APEX can create value within your business operations.

What is Oracle APEX

Oracle APEX is Oracle’s enterprise low-code platform for building secure, scalable applications. It runs directly inside Oracle Database and can be deployed on-premises, in Oracle Cloud Infrastructure (OCI), or in hybrid environments.

With more than 20 years of evolution—starting as HTML DB and maturing into the modern APEX platform—it has become a fully enterprise-ready solution with a rich feature set and frequent releases.

Low-code platforms were designed to address the challenges of long and costly custom development by reducing the need for hand-coding. They provide visual development tools, prebuilt components, and automation features that allow teams to deliver applications faster and with fewer resources. Like other low-code platforms, APEX accelerates delivery: what once took months of custom development can now be achieved in weeks by smaller teams.

What sets Oracle APEX apart is its architecture. Unlike standalone tools, APEX runs natively within Oracle Database, which means performance, security, and governance are built in—not added as extra layers. You already own the foundation; the real question is what you will build on top of it.

Oracle APEX key features and capabilities

Oracle APEX combines speed, flexibility, and enterprise-grade resilience. It enables developers and business teams to build applications quickly while maintaining the robustness required at scale.

Oracle’s promise is that an environment that is up to 20x faster than traditional custom development and far more flexible than off-the-shelf software. Indeed, having developed dozens of APEX solutions for our clients, it does take a fraction of resources.

However, foundations in the knowledge of code and how database functions are essential to fully leverage these capabilities. Without the right approach and following best practices, enterprises might end up with a complex application that would be difficult to maintain. Especially when the business scale. Some of the key capabilities include:

Rapid UI building

Oracle APEX comes with predefined components and wizards that make it possible to build user interfaces rapidly. Developers can create forms, reports, interactive grids, and charts in weeks instead of months, all directly powered by your Oracle Database. Workflows and approvals can also be added declaratively, digitizing processes without heavy custom coding.

Role-based security and auditability

Security is built into the core of APEX. It supports Single Sign-On (SSO), OAuth2, LDAP, and Database Accounts for authentication and authorization. Every action can be logged, giving enterprises full auditability across users, sessions, and transactions—critical for governance and compliance.

20x faster than custom development

Compared to multi-tier custom stacks, APEX applications can be delivered up to 20 times faster. Smaller teams can build complete apps by reusing PL/SQL and leveraging Oracle Database capabilities directly. With fewer moving parts, development cycles are shorter and maintenance is simpler.

Flexibility and customization

Unlike SaaS modules that require you to adapt your processes to fit the software, APEX lets you tailor applications to your organization. Native Oracle integration ensures data and processes stay close to the system of record, while avoiding “SaaS sprawl” and per-module license costs.

Modern data and AI

Oracle APEX supports a wide range of data types, including relational tables, JSON, REST sources, and files. Its built-in AI features enhance both development and end-user experiences: developers can use AI-assisted code generation, text-to-SQL, and code explanations, while end-users can leverage vector search, text generation, and conversational AI to gain faster insights.

Easy data exploration

Interactive Reports and Interactive Grids make it simple for end-users to work directly with enterprise data. They can search, filter, pivot, and edit data. Faceted Search and Smart Filters allow users to quickly narrow results through checkboxes, ranges, or keyword search—giving non-technical users powerful self-service exploration.

Powerful visualizations

With Oracle JET and other charting options, APEX includes several visualization types—from bar, line, and pie charts to Gantt and funnel charts. These charts are interactive, responsive, and can be embedded directly into dashboards, transforming raw data into actionable insights.

Forms and data processing

APEX simplifies the creation of responsive, database-driven forms. Built-in data processing automates row fetching and updates, and optimistic locking ensures multiple users can edit safely. Data captured through forms can be reused instantly—in reports, dashboards, or as input for ERP and other connected systems.

Seamless data integration

Integration is a core strength of APEX. It supports Oracle ERP, E-Business Suite, JD Edwards, and Fusion add-ons, while also working with non-Oracle systems via REST/JSON APIs. Database links make it possible to connect directly to other Oracle databases and, through ODBC, to non-Oracle databases. APEX also integrates with RPA and BI tools, ensuring enterprise systems work together smoothly.

Mobile-friendly

Applications built in APEX are responsive by default, meaning in most cases they adapt to desktops, tablets, and mobile devices. This ensures a consistent user experience across devices, whether for employees in the field, executives on the move, or back-office staff at their desks. Keep in mind that some modules, such as Interactive Grids, are not responsive. Make sure to take this into account when planning the rollout for mobile devices.

Why Enterprises Should Care

Oracle APEX delivers faster development cycles and measurable business outcomes. Enterprises using APEX can deliver applications up to 20x faster, run with up to 100x less infrastructure, and pay no per-user licensing fees because it’s already included with your Oracle Database.

For directors and executives, the value of Oracle APEX has direct business implications:

• Endless value creation. Create enterprise applications that connect with your existing systems and scale across departments, enhancing core processes, uncover new efficiencies, and open up opportunities for entirely new revenue streams. The result is the ability to do more, faster, with the same resources—driving growth and optimizing costs simultaneously.
• Lower total cost. APEX eliminates per-user fees and minimizes infrastructure requirements because it’s already included in Oracle Database. There’s no need for costly subscription licenses, and development itself is more efficient—cheaper and faster than traditional custom coding.
• Operational impact. Replace spreadsheets, paper-based processes, and shadow IT with secure, auditable applications. Manual work becomes automated, freeing your talent for higher-value tasks. Processes become transparent across the organization, reducing risk and improving decision-making.
• Capacity without overhiring. APEX empowers your existing Oracle and SQL teams to deliver solutions quickly, bringing in specialists only when needed. Just as importantly, the applications themselves allow your business to scale without proportional increases in headcount—because automation frees staff to focus on growth.
• Governance and compliance. With APEX, data, logic, and controls stay centralized in Oracle Database. Integration with Oracle Access Governance means administrators can easily view who has access to sensitive data and what permissions are assigned, ensuring compliance with internal and external regulations.
• Security. APEX leverages Oracle’s enterprise-grade security framework, including Single Sign-On (SSO), OAuth2, LDAP, encryption, and session-state protection. Security is built in from the start—not added later—ensuring your applications meet enterprise standards from day one.
• ERP augmentation. In most cases, replacing your ERP doesn’t make sense. APEX lets you extend ERP and core systems with new workflows, dashboards, and modules, unlocking more value without disruption. You can enhance existing investments instead of replacing them.

Oracle APEX gives enterprises a platform to innovate continuously while keeping costs predictable, security strong, and operations aligned with business growth. APEX is a strategic enabler for digital transformation.

These examples show how with the right approach, APEXdelivers enterprise-grade systems that replace legacy processes and drive measurable ROI.

Pricing and cost considerations

Oracle APEX is included with Oracle Database and Autonomous Database. There are no per-user or per-application fees, which makes it far more cost-effective than many low-code competitors. For enterprises already invested in Oracle, this is especially compelling—you leverage the database you already own without paying for additional licenses.

The total cost of building and running APEX applications depends on four primary factors: -** License.** APEX itself comes at no extra cost; it’s bundled with Oracle Database.

• Build. The complexity of the application and the number of systems integrated determine development effort. Simple apps can often be delivered in weeks by a single developer, while larger enterprise systems require more planning but still come faster and cheaper than custom development.
• Deployment. Enterprises can deploy on existing on-premises infrastructure or Oracle Cloud Infrastructure (OCI). OCI provides elastic scaling, automated backups, and reduced operational overhead, while on-premises may be preferable for organizations with strict residency requirements.
• Maintenance. Declarative updates, shared components, and standardized UX significantly reduce long-term maintenance costs compared to traditional custom apps, where every change requires custom coding.

Oracle APEX’s cost vs custom development

Traditional multi-tier custom development typically requires larger teams, longer timelines, and more infrastructure. Each layer—front end, middleware, database—needs specialized skills and dedicated environments. This complexity drives up both build and maintenance costs. APEX, by contrast, eliminates most of that overhead by running natively in Oracle Database. Enterprises can reuse existing PL/SQL skills, shorten delivery cycles by up to 20x, and run with significantly less infrastructure.

APEX:

• Lower build cost. Smaller teams, reuse of PL/SQL, and delivery up to 20x faster than custom development.
• Cheaper infrastructure. Runs entirely inside Oracle Database with far fewer moving parts.
• Lower maintenance. Declarative updates, shared components, and standardized UX reduce ongoing effort.
• Faster ROI. Lower upfront investment and shorter time-to-value.

Oracle APEX’s cost vs SaaS solutions

Ready-made SaaS applications are quick to adopt, but they often force you to adapt your processes to fit the software. Licensing is typically subscription-based, charged per user, module, or transaction—which adds up quickly as your organization grows.

There’s also a long-term complexity cost: if you adopt a separate SaaS tool for every process—CRM, onboarding, expenses, compliance, HR—you end up with dozens of disconnected apps. Each has its own license, integration challenges, and data silos, creating IT overhead that becomes difficult and costly to manage.

APEX gives you one platform, one database, and endless applications you can layer up on your existing system. You build what you need, tailored to your processes, with full control over data and governance. Instead of spreading resources across multiple SaaS tools, you consolidate on a single enterprise-grade platform.

APEX:

• More expensive build cost. SaaS has almost no build cost—you subscribe and start. APEX apps require upfront development effort.
• Cheaper licensing long-term. No per-user or per-application fees; SaaS costs scale with usage (per user, per module, or per transaction).
• Lower IT overhead. One platform for many apps; SaaS often means managing dozens of disconnected tools.
• Lower maintenance cost. Declarative updates, shared components, and standardized UX reduce ongoing effort, while SaaS upgrades often require extra configuration or disrupt integrations.

Migrating from Oracle Forms to Oracle APEX

Oracle Forms, part of Oracle Fusion Middleware, has been a cornerstone for building data-driven apps since the 1990s. It allowed enterprises to create form-based UIs that connected directly to Oracle Databases, powering thousands of mission-critical systems across industries.

While powerful in their time, Oracle Forms applications are rooted in client-server architecture and often depend on legacy technologies. Over time, this makes them harder to maintain, integrate, and scale—especially in a cloud-first, mobile-driven world. Oracle continues to support Forms, but modernization is increasingly necessary to meet user expectations and business demands.

Why it’s worth moving from Forms to APEX

Modernizing Oracle Forms with Oracle APEX offers clear advantages:

• Lower costs. Because APEX is bundled with Oracle Database, enterprises avoid the additional licensing fees that Oracle Forms requires, cutting overall ownership costs.
• Modern user experience. APEX apps are responsive by default, mobile-ready, and intuitive, which means employees need little to no training to adopt them.
• Enterprise-grade apps. Workflows, charts, REST services, maps, and AI assistance are available out-of-the-box, allowing to build applications that create business impact.
• Flexible deployment and scalability. Applications can run on-premises or in the cloud, scaling smoothly from small teams to tens of thousands of concurrent users.
• Quick and seamless migration. Business rules and PL/SQL code built for Forms can be carried over into APEX and Forms and APEX can run side by side. It both accelerates migration and allows a gradual, low-risk modernization strategy.
• Transferable skills. Both platforms are database-centric and use SQL and PL/SQL. Developers with Oracle skills can upskill into APEX quickly, often becoming proficient within weeks rather than months or years.

How to migrate from Oracle Forms to APEX

Moving from Oracle Forms to Oracle APEX doesn’t have to be a disruptive, all-at-once project. The most effective approach is phased and pragmatic:

1. Start small. Select a clearly defined, high-impact process or module from your existing Forms environment to modernize first.
2. Get your foundation ready. Review the database objects and business logic you already have, and plan how they will be reused inside APEX.
3. Rebuild and enhance. Use APEX’s built-in wizards to recreate forms and reports quickly, then layer on modern features like dashboards, workflows, or mobile access.
4. Roll out gradually. Deploy the new APEX application in Oracle Cloud Infrastructure or on-premises, integrate it with your existing systems, and scale adoption step by step.

The result is smoother user adoption, easier maintenance, and a future-proof platform aligned with Oracle’s product strategy.

Oracle APEX and AI

Oracle APEX includes native AI features that enhance both development and end-user experiences. By combining low-code with generative AI, APEX makes delivery cycles even faster and enterprise applications more intelligent and accessible.

AI-assisted development

With the APEX AI Assistant, developers can generate, optimize, and debug SQL queries, as well as get help with HTML, CSS, JavaScript, and PL/SQL—all using natural language. You can even describe the kind of app you want and APEX will scaffold it for you, creating data models and page blueprints in seconds.

That said, AI-generated code should still be reviewed and validated. Understanding the logic behind the application ensures that it remains maintainable in the long run, avoids unnecessary complexity, and doesn’t introduce odd or inefficient snippets. Think of code as an investment: the cleaner and more deliberate it is, the lower your maintenance burden and the higher your return over time.

AI-powered applications

AI has become an essential part of modern enterprise applications, helping organizations unlock insights, improve user experiences, and automate tasks. Of course, not every feature needs to be powered by AI—sometimes the simplest declarative tools are the right solution. But it’s important to remember that APEX gives you the option to embed it seamlessly into your applications.

Conversational dialogs let users interact naturally with systems, while retrieval-augmented generation (RAG) ensures responses are precise and relevant. Built-in vector search allows semantic similarity searching, and integration with OCI AI services adds capabilities like image recognition, transcription, and natural language processing.

With APEX, AI is built in. Developers build faster, end-users work smarter, and enterprises unlock new ways to create value from their data.

Choosing the Right Oracle APEX Partner

Implementing Oracle APEX at enterprise scale requires more than just technical expertise. It calls for a partner who understands both the technology and the business outcomes you need to achieve. Every application should begin with clearly framing the process or problem it is meant to support. From there, it’s essential to have the right resources in place to ensure the solution follows best practices and delivers results in the most effective way.

Deep knowledge of Oracle Database and PL/SQL

Since APEX runs natively inside Oracle Database and it’s essentially a tool to create value out of your database, the partner must understand database architecture, performance tuning, and PL/SQL. It’s more important that the developers have experience and understanding working with databases over a general development skills. They need to understand how to connect systems etc so the whole thing runs smoothly. These are critical enterprise apps—so you want to make sure that the data you input will end up where it needs to.

Proven track record with enterprise APEX projects

It’s not enough to build a simple form or workflow. Look for a partner with experience delivering complex, multi-department applications that integrate into enterprise systems and generate measurable ROI. Focus on the outcomes they’ve achieved—how much time was saved, what additional revenue was created, which teams benefited, and in what ways. The emphasis should be on results, not just the number of apps produced. Building a demo app in APEX is easy; building an application that directly drives business outcomes requires true business understanding.

Integration expertise with Oracle ERP and third-party systems

Enterprise applications rarely operate in isolation. For APEX projects to succeed, they must integrate seamlessly with Oracle ERP, E-Business Suite, Fusion, JD Edwards, and often with non-Oracle systems through REST APIs, RPA, or BI tools. The right partner brings experience across multiple systems, takes a technology-agnostic approach, and understands not only how these platforms work individually but also how to connect them into a unified enterprise ecosystem.

Pre-built modules and accelerators for faster delivery

The strongest partners don’t reinvent the wheel. Their value comes from extensive experience building enterprise systems, which means they already have reusable modules and accelerators—like onboarding workflows, approval chains, or even a full CRM platform—that can be adapted to your needs. With minor adjustments, a solution developed for one client can often be tailored to another, significantly reducing delivery time and cost. This applies not only to small departmental apps but also to complex, multi-module systems, where leveraging proven components ensures faster implementation and higher reliability.

Training and knowledge transfer programs

Sustainable success means empowering internal teams, not creating dependency. A reliable partner will prioritize knowledge transfer and post-deployment support, ensuring your Oracle and SQL specialists can extend and maintain applications with confidence. Make sure the partner you choose is as focused on building your team’s capability as they are on delivering the initial solution.

Ongoing SLAs and support aligned with Oracle’s roadmap

APEX evolves quickly, with regular releases introducing new features and improvements. To keep pace, your partner should provide clear SLAs and structured support that go beyond troubleshooting. This includes monitoring performance, applying updates, and helping your team adopt new capabilities as they are released. The goal is to ensure your applications stay secure, optimized, and fully aligned with Oracle’s long-term roadmap.

How to Build a Simple App in Oracle APEX

Even complex journeys start small. The key is to approach your first APEX app with structure and clarity:

1. Discovery

Start with mapping the entire process or system. This will help you understand the workflow, and identify bottlenecks, pain points, and the stakeholders affected. The goal is to uncover where the biggest business impact lies. Where possible, assign ROI to the opportunity, but also consider less measurable benefits. Some outcomes—like faster compliance checks or fewer manual handoffs—don’t translate neatly into numbers, yet they reduce errors, increase transparency, and improve trust in the system.

2. Solution design

Once the problem is clearly defined, design a solution roadmap. This includes outlining the application’s core functions, identifying the necessary data sources, how it ties into existing systems, and defining roles and compliance rules. At this stage, it’s also useful to create blueprints or prototypes and link them to projected ROI or tangible outcomes. This helps decision-makers prioritize initiatives based on value, feasibility, and urgency.

3. Setup

Before development begins, the environment needs to be ready. Because APEX runs inside Oracle Database, setup involves ensuring the platform is installed and licensed correctly, choosing whether to deploy on-premises or in Oracle Cloud Infrastructure (OCI), and preparing integration points with other systems. A smooth setup is crucial to avoid costly disruptions later and ensures a secure, scalable foundation for your applications.

4. Development

With the groundwork in place, start development of the app. APEX wizards accelerate scaffolding for forms, reports, and dashboards, but the true value comes from tailoring the solution to your processes. Development should include integration with ERP and other enterprise systems so that the app doesn’t stand alone but fits naturally into the larger IT landscape. The focus here is on balancing speed with maintainability—clean code and best practices ensure long-term scalability.

5. Iteration and improvement

Not always necessary, but in some cases a minimum viable product (MVP) is critical. Early releases let users test the app in real-world conditions, which generates valuable feedback. Especially, when you are having difficulties in change management. Involving your team within the process (from discovery through development and testing), will help with adoption and getting their buy in. Monitor performance and measure ROI or qualitative improvements. Quick wins at this stage build credibility and confidence across the business.

6. Maintenance

Once the app is in production, the journey doesn’t stop. Maintenance involves monitoring performance, applying updates, and continuously aligning the application with best practices and Oracle’s roadmap. Post-deployment support is also about enabling internal teams to own and extend the solution over time. This ensures apps don’t stagnate and continue to deliver value as business needs evolve.

Is your team using APEX to its full potential?

For enterprises already running on Oracle Database, Oracle APEX is within reach. The real question is whether you’re using it strategically—or just scratching the surface.

By applying best practices, modernizing legacy systems, and leveraging APEX’s integration and AI features, enterprises can digitize faster, reduce costs, and strengthen governance. Ignore it, and you risk higher maintenance costs, slower change cycles, and competitive disadvantage.
